The Epicenter Billet – a limited-run tribute to an AudioControl
fan favorite – delivers the same powerful performance as
the original, with a sleek new aesthetic. Built on the trusted Epicenter Concert Series platform, it features AudioControl’s patented digital bass restoration circuitry that analyzes incoming audio signals, recreates missing low-end frequencies, and injects them back into the signal path – dramatically enhancing bass response.

It’s packed with powerful tuning tools, including parametric bass control and a subsonic filter, giving you precise control over your system’s low-end performance. This special edition sports
a black solder mask PCB, updated silkscreen logo, crisp white LEDs for Epicenter and power status, and an aluminum knob finished to match the billet chassis for a seamless, premium look.

Restore the earth-shaking power and heart-pounding bass your subwoofers crave – now in a bold new billet design.

ACR-1 Remote Level Control is included.
